SPRING-HINGE.

Application filed August 19, 1915.

To all whom it may concern Be it known that I, J AMES E. CLAY, a citizen of the United States, and a resident of Sharpsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Spring-Hinges, of which the following is a specification.

This invention relates to hinges, and particularly to a spring hinge for use with screen doors, storm doors, hinged window screens and the like.

The object of the invention is to provide a hinge of this character which is of simple construction and can be sold at low cost, which can be readily manufactured and assembled, and which enables the door or other device to be lifted off from its hinges without detaching the hinge leaves from the door or frame, or in other words, a spring hinge the leaves of which are readily detachable.

A further object of the invention is to provide a detachable spring hinge in which the spring is attached to the part carried by the door, so that when the door is removed for storage during the winter the spring is indoors and protected from the weather.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter. I

In the drawings, Figure l is an elevation of one form of hinge embodying the invention; Figs. 2 and 3 are similar views of the two leaves of the hinge detached from each other; Figs. l and 5 are end views of the two hing leaves detached; and Fig. 6 is a view corresponding to Fig. 5 and showing how the spring is manipulated in assembling the two parts of the hinge.

The hinge shown in the drawings comprises a leaf 1 to be attached to the door frame, for which purpose it is provided with one or more screw-holes 2, as is usual. At its lower end said leaf is provided with an outwardly extending ear 3 to support the pin or pintle a, which is riveted or otherwise secured to said leaf and extends upright thereon with its axis in the plane of said leaf but spaced therefrom, as shown in Fig. 2. The other leaf of the hinge, marked 5, is also provided with screw-holes 6 for attaching it to the door. Said leaf is provided with a hollow sleeve 7 to fit over the pintle 4: to

form the pivot for the hinge. This sleeve may be attached to the leaf 5 in any suitable manner, and is shown as passing at its opposite ends through parallel ears 8 bent out Specification of Letters Patent.

from the material of the leaf 5, the sleeve 7 being headed over on the outside of said leaves or otherwise attached rigidly thereto, as will be readily understood. Coiled about the sleeve 7 is a suitable spring 9, which in manufacture of the device is placed between the ears 8 of the leaf 5 before the sleeve 7 is attached thereto. One end of said spring, such as its lower end 10, extends outwardly and lies parallel with and closely contiguous to one of the leaves, such as the leaf 5, which forms a point of purchase therefor. The other end of the spring extends outwardly from the sleeve 7 and is bent at its outer end to form a loop 11, which can be grasped with the fingers to tighten up the spring in as sembling or disassembling the two parts of the hinge.

The two leaves 1 and 5 of the hinge are separately attached to the frame and door respectively. The spring is tightened up by pulling the loop 11 outwardly from the position shown in Fig. 5 to the position shown in Fig. 6, which enables the sleeve 7 to be dropped over the pintle i and also enables the upper end of the spring forming the loop 11 to pass down beyond the upper edge of the leaf 1 so that it lies in front thereof. This leaf may, if desired, extend slightly above the upper end of the pintle l, although this is not essential. In this position of the parts the opposite ends of the spring engage the two leaves 1 and 5 and thereby place the spring under tension when the door is opened and close the door when released. The door can be readily removed at any time by merely tightening up the spring sufiiciently to allow the sleeve 7 to be lifted off from the pintles.

This hin 'e is very simple and can be made and sold at low cost and enables a screen door, storm door or hinged window screen to be readily attached to and detached from the frame without unscrewing the hinge leaves.

The hinge may be made in rights and lefts to enable it to be attached to either edge of the door, although it can be reversed and the leaf 5 attached to the frame and the leaf 1 to the door, if desired. It is preferable, however, to always attach the leaf 5 to the door so that the spring follows the door to storage and is protected against the weather.

What I claim is 1. A hinge, comprising a leaf, a pintle at- Patented Maylfi', 1916.

tached at one end thereto, a second leaf provided with two ears, a sleeve connecting said ears and fitting over said pin, and a spring coiled around said sleeve and at its opposite ends engaging said leaves.

2. A hinge, comprising a leaf, a pintle at tached at one end thereto, a second leaf pro vided with a sleeve fitting over said pin, and a spring coiled around said sleeve and at its opposite ends engaging said leaves, said spring being bent to form a finger hold for tightening up said spring in assembling or disassembling the hinge.

3. A hinge, comprising a leaf, a pintle attached at one end thereto, a second leaf provided with tWo ears, a sleeve connecting said ears and fitting over said pin, and a spring coiled around said sleeve and at its opposite ends engaging said leaves, said spring being bent to form a finger hold for tightening up said spring in assembling or disassembling the hinge.

4. A hinge, comprising a leaf, a pintle attached at one end thereto, a second leaf pro vided with a sleeve fitting over said pin,

Copies of this patent may be obtained for five cents each, by addressing the and a spring coiled around said sleeve and at its opposite ends engaging said leaves, the axis of said pin and sleeve being parallel with the planes of said leaves.

5. A hinge, comprising a leaf, a pintle attached at one end thereto, a second leaf provided with two ears, a sleeve connecting said ears and fitting over said pin, and a spring coiled around said sleeve and at its op osite ends engaging said leaves, the axis of said pin and sleeve being parallel With the planes of said leaves.

6. A hinge, comprising a leaf having an ear at one end, a pintle attached at one end to said leaf said leaf extending above the end of said pintle, a second leaf provided with a sleeve fitting over said pin, and a spring coiled around said sleeve and at its opposite ends engaging said leaves.

In testimony whereof, I have hereunto set my hand.
